Mathematics
1 answer:
lesantik [10]2 years ago
5 0

Answer:

the equation should have been 20/_200_= 10/100

Step-by-step explanation:

the error kate made was that she put 20 as the denominator instead of the numerator. putting 20 as the denominator implies that kate attempted a total of 20 free throws. But that's not the case. 20 should have been the numerator because thats the amount of free throws she made and we are trying to figure out the total amount she attempted.

Lin is reading a 47-page book. She read the first 20 pages in 35 minutes. A: if she continues to read at the same rate, will she
Elena L [17]

Answer:

No

Step-by-step explanation

Because 20 more pages would take 35 more minutes which would be 40 pages at 70 mines then you will divide your 7 pages left by the 35 minutes it took to read the the first two 20 page sections of the book.

35 min.+ 35 min = 70 min.  35 mins./7 pages = 5 mintes

So it took a total of 75 minutes for Line to read her 47 page book.

If f(1)=4f(1)=4 and f(n)=f(n-1)^2+2f(n)=f(n−1) <br> 2<br> +2 then find the value of f(3)f(3).
gogolik [260]

Answer:

f(3) = 326

Step-by-step explanation:

Given the function

f(n)=f(n-1)^2+2

If f(1) = 4

f(2) = f(1)^2 + 2

f(2) = 4^2 + 2

f(2) = 16 + 2

f(2) = 18

f(3) = f(2)^2 + 2

f(3) = 18^2 + 2

f(3) = 324 + 2

f(3) = 326

Write the sum using summation notation, assuming the suggested pattern continues.
Usimov [2.4K]

Answer:

Sum of the sequence will be 648

Step-by-step explanation:

The given sequence is representing an arithmetic sequence.

Because every successive term of the sequence is having a common difference d = -3 - (-9) = -3 + 9 = 6

3 - (-3) = 3 + 3 = 6

Since last term of the sequence is 81

Therefore, by the explicit formula of an arithmetic sequence we can find the number of terms of this sequence

T_{n}=a+(n-1)d

where a = first term of the sequence

d = common difference

n = number of terms

81 = -9 + 6(n - 1)

81 + 9 = 6(n - 1)

n - 1 = \frac{90}{6}=15

n = 15 + 1 = 16

Now we know sum of an arithmetic sequence is represented by

\sum_{n=1}^{n}(a_{n})=\frac{n}{2}(a_{1}+a_{n})

Now we have to find the sum of the given sequence

S_{16}=\frac{16}{2}[-9 + (16-1)6]

              = 8[-9 + 90]

              = 8×81

              = 648

Therefore, sum of the terms of the given sequence will be 648.
